From e50cb8b2f440aa590f06dde0b592b312fafc85eb Mon Sep 17 00:00:00 2001 From: James Almer Date: Sun, 23 Sep 2018 21:54:24 -0300 Subject: [PATCH] avformat/ivfenc: fix writing codec tag MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The value in AVCodecParameters->codec_tag may not be correct for IVF, as it's the case when remuxing AV1 streams from mp4, so ignore it and write the correct value based on codec ID instead.
